I recommend that you work with a business broker. Make sure that the broker is your agent and not the sellers agent. Similar to the real estate market, the business broker is responsible for protecting your interest if they are YOUR agent.
Additionally, they will direct you to seeking the advice of a lawyer and CPA where and when applicable.
I would highly suggest that you clearly understand why the current owner is looking to sell. Many will list other interests or health problems when in fact there may be other problems plaguing the business. You will need to know what these problems are and determine if you want to or can turn them around.
Regarding financing, you will need a good business plan to present to a lender. Depending on the amount you request for financing, the health of the business, the ability to repay the loan, the economic health of the market that you are serving, your experience in this type of business, your credit history and your collateral, the lender will determine how much you will need to come in with.
As Ichiban mentioned above, you may be able to work out a seller carry-back agreement for either the total amount or for the balance that a lender requires. With a seller carry-back, the seller typically carries the note for a shorter period of time with balloon payments both at the beginning and at the end of the note. You may be able to work out a good deal with the seller on a carry-back note if they would incur tax repercussions by taking a total cash payout at closing.
Good luck.
